<p>"问题在于，我正试图通过Client浏览器发起的请求将文本内容写入服务器端文件。NOTE:这已经是相当长的时间以来，我对TypeScript/PHP/服务器的工作了，所以请不要假设我默认就知道一切：）我根据自己的代码进行了修改：/问题/11240996/将JavaScript输出到文件中-server<br /><br />我最终得到了一个使用PHP服务器端创建文件"h.txt"的代码。确实是创建了一个空文件"h.txt"，但它的内容"456"从未写入：我从未收到关于原因的错误消息。"456"是文件的内容，</p><p><br /></p> <h2>服务器端</h2> <pre class="brush:php;toolbar:false;">//PHP code: (A little elaborate, but it should work) //h.txt is created, but its content is never written: read only problem?? I can't find how to see if //the file is read only or not) //The php Code is located on Server &lt;?php function getData() { $myFile = fopen("h.txt", "w"); fclose($myFile); sleep(5); //return "link to h.txt"; } getData(); // Tried to return different values for the URL below: // "h.txt" is created, but its content "456" is never // written return "URL to h.txt"; ?&gt;</pre> <pre class="brush:php;toolbar:false;">//On the Client side I have the following code: //The Client is written in Angular, and the function that triggers the data exchange with server testWriteToServerFile() { let data: string = "456";// this is your data that you want to pass to the server //next you would initiate a XMLHTTPRequest as following (could be more advanced): var url = url to the server side PHP code that will receive the data. var http = new XMLHttpRequest(); http.open("POST", url, true); //Send the proper header information along with the request http.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http.setRequestHeader("Content-length", data.length.toString()); http.setRequestHeader("Connection", "close"); http.onreadystatechange = function() {//Call a function when the state changes. if(http.readyState == 4 &amp;&amp; http.status == 200) { alert(http.responseText);//check if the data was received successfully. } } http.send(data); }</pre> <p>(我试图包括适当的链接到服务器等，但这篇文章被归类为垃圾邮件?)<br /><br />服务器上的h.txt对客户端是只读的问题吗?解决方案是什么?<br /><br />我希望能够将文本写入服务器上的h.txt文件。</p><p><br /></p>

function getData() {
  $myFile = fopen("h.txt", "w");
  fclose($myFile);
  sleep(5);

function getData() {
$myFile = fopen("h.txt", "w");
fwrite($myFile, filter_input(INPUT_POST, 'data', FILTER_SANITIZE_SPECIAL_CHARS));
fclose($myFile);
